Superior mesenteric artery syndrome: case report.

Superior mesenteric artery (SMA) syndrome is a rare acquired disorder in which acute angulation of SMA causes compression of the third part of the duodenum between the SMA and the aorta, leading to obstruction. Loss of fatty tissue as a result of a variety of debilitating conditions is believed to be the etiologic factor causing the acute angulation. We report a case of 30 years old lady who presented with postprandial abdominal pain at the epigastric region, colic type without radiation accompanied by nausea, postprandial vomiting and weight loss. Esophageal gastric series revealed an abrupt interruption in the contrast medium flow at the level of the junction of third portion (midpart) of the duodenum in barium studies. Adiverticula is noted just proximal to the site of obstruction. High resolution ultrasound and color Doppler sonography showed narrowing of the aortomesenteric angle to 220. Duodenojejunostomy was performed in the patient. Unfortunately the patient later was admitted in the hospital for refractory gastroparesis associated with superior mesenteric artery syndrome. Although open and laparoscopic duodenojejunostomy have been described as the best surgical treatment options for Wilkie's syndrome, but further attention is needed to the management of patients with refractory symptoms of gastroparesis after corrective surgery.
